Members of the genus Campylobacter are commonly found in the
gastrointestinal tract of mammals and birds, and can be commensal
or pathogenic in nature. In this book, internationally recognized
experts critically review and provide novel insights into important
aspects Campylobacter research.
Freshwater eels are almost infinitely improbable creatures. They
spawn and die in the middle of the ocean, often associated with
undersea mountains. Their tra- parent, leaf-like larvae move with
ocean currents for months or years until they approach the mouths
of freshwater rivers. Then they undergo a dramatic transf- mation
in morphology, physiology and behavior. They move from their
planktonic oceanic environment, migrate upstream and live for
several years as apex fre- water predators. Then, almost
impossibly, as they become sexually mature, they reverse their
migration downstream to the ocean and back to spawning grounds to
complete their life cycle. The dramatic changes in their life
cycles are incredible. The efforts to unravel the details of their
life history have been truly daunting. Much of the past research
was the work of dedicated individuals who devoted their lifetime
research to these fishes. Freshwater eels merit a separate chapter
in almost any textbook dealing with ichthyology, marine biology or
animal migration. We know a great deal about some aspects of the
biology of freshwater eels. However, our understanding of their bi-
ogy still resembles a work of art as much as a work of science. To
some it appears like the sweeping brush strokes of a Japanese Zen
landscape, to others it resembles the work of a French
impressionist, and to still others it appears as magic realism.
There are many books on biological control, but this will bring up
to date the regulatory and other specific challenges facing
biological control, and how they are being met. It is the first
book to bring together a comprehensive account of global activities
in biological control, region-by-region, amalgamating information
from introduction biological control, conservation biological
control and augmentative biological control (including commercial
use). Offers a historical summary of organisms and main strategies
used in biological control. Outlines key challenges confronting
biological control in the 21st century and describes the main
socioeconomic challenges that need to be addressed. Global
overview: summarises biological control efforts around the globe
and highlights important successes and failures, providing
suggestions to best move biological control forward in a changing
world. Biological control is a fairly specialized field but one
that is spread across a broad array of socio-environments in
agriculture and public health around the world. There is also a
significant regulatory component to a subset of this field
(classical biological control) that researchers must navigate to
achieve the aims of their research and its application. This book
will help!

This is the companion volume to Daniel Klionsky s "Autophagy: Lower
Eukaryotes, " which features the basic methods in autophagy
covering yeasts and alternative fungi (aspergillus, podospora,
magnaporthe). Klionsky is one of the leading authorities in the
field. He is the editor-in-chief of "Autophagy." The November 2007
issue of "Nature Reviews" highlighted his article, Autophagy: From
phenomenology to molecular understanding in less than a decade. He
is currently editing guidelines for the field, with 230
contributing authors, that will publish in "Autophagy."
Particularly in times of stress, like starvation and disease,
higher organisms have an internal mechanism in their cells for
chewing up and recycling parts of themselves. The process of
internal house cleaning in the cell is called autophagy - literally
self-eating. Breakthroughs in understanding the molecular basis of
autophagy came after the cloning of ATG1 (autophagy-related gene 1)
in yeast. (To date, 30 additional yeast genes have been
identified.) These ATG genes in yeast were the stepping stones to
the explosion of research into the molecular analysis of autophagy
in higher eukaryotes. In the future, this research will help to
design clinical approaches that can turn on autophagy and halt
tumor growth."

Progestins play a key role in reproductive endocrinology and as
pharmaceutical drugs for contraception and in combined hormone
therapy. To further our understanding of progestin action in the
mammary gland, an international symposium, attended by leading
researchers from academia and industry, was held in Berlin, 21 23
March 2007. Genetic mouse models helped to elucidate the role of
progestins, both in normal breast development and in disease.
Mechanistic molecular studies inspired the design of new progestins
with improved tissue selectivity. In addition, the clinical impact
of progesterone receptor agonists and antagonists for the
prevention and treatment of breast cancer was discussed.
This book focuses on explaining the distribution of sexual systems
(simultaneous hermaphroditism, sequential hermaphroditism,
environmental sex determination,dioecy, androdioecy, etc.) among
taxa, which remains a major challenge in evolutionary biology.
Although significant advances have been made for angiosperms, there
is not yet a theory that predicts the sexual system for the
majority of animal taxa, and other taxa of plants also remain
poorly understood. The problem, particularly for animals, is that
sexual systems can be very conservative, with whole phyla and
classes being characterized by a single sexual system; for example
essentially the whole phylum Platyhelminthes is simultaneously
hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda
among the vertebrates, are exclusively dioecious. Sex allocation
theory on the other hand, suggests that sexual systems should be
highly responsive to evolution, changing with population density,
life span, patterns of resource availability, etc. The book
provides an overview of the topic and then presents a series of
chapters, each dealing with a taxon with substantial lability in
sexual system in order to identify the factors associated with
changes in sexual system in each case. By doing so, the authors
reveal factors that have not been considered in formal theory but
seem to have a major impact on transitions between sexual systems.
This book appeals to a wide readership in fields from zoology and
evolutionary biology to botany.
"Vascular Morphogenesis: Methods and Protocols" provides a range
of techniques for studying vascular morphogenesis in vivo and in
vitro, reflecting advances in the field. Endothelial cell signaling
is currently believed to promote fundamental cues for cell fate
specification, embryo patterning, organ differentiation and
postnatal tissue remodeling. Understanding the concept of vascular
bed specificity represents a major challenge for future
investigations. Indeed, one of the most interesting theoretical
perspectives and practical applications of endothelial cell
signaling is the possibility for these cells to maintain their
inductive potential during adult life. Written in the highly
successful "Methods in Molecular Biology" series format, chapters
include introductions to their respective topics, lists of the
necessary materials, step-by-step, readily reproducible laboratory
protocols and tips on troubleshooting and avoiding known
pitfalls.
Practical and authoritative, "Vascular Morphogenesis: Methods
and Protocols" will serve as a instructive and useful reference for
cell biologists, anatomists, pathologists and physiologists, as
well as all those interested in this area of biological study.
This is a how-and-why-to-do-it book for students and scientists in
all the behavioral sciences. It presents sophisticated statistical
methods for analyzing continuous-time records of behavior, and
integrates many recent developments in ethology, mathematical
modelling, statistics, and technology. These new methods are
explicitly designed to handle sequential or simultaneous acts where
neither the duration nor the sequence of the acts is predetermined,
which is often the case if the time scale on which behavior is
studied is relatively short. The authors show how to analyze
behavioral data starting with a basic model, the continuous time
Markov chain. They then indicate how and when this model can be
generalized and demonstrate the suitability of their approach for
detecting, for example, the effects of different experimental
treatments or of gradual changes in the social or physical
environment. Competitive interactions such as predator-prey or
host-parasite are also good subjects for this type of analysis.
There are eight chapters and many worked examples, leading the
reader through the mathematical processes and their applications.
Students and researchers in all fields of behavioural science will
find this book incomparably useful for planning and performing data
analysis.
'Jackie Higgins's lyrical, literate style will charm you while her
book stuns your imagination with strange, other-worldly truths'
Richard Dawkins Sentient assembles a menagerie of zoological
creatures - from land, air, sea and all four corners of the globe -
to understand what it means to be human. Through their eyes, ears,
skins, tongues and noses, the furred, finned and feathered reveal
how we sense and make sense of the world, as well as the untold
scientific revolution stirring in the field of human perception.
The harlequin mantis shrimp can throw a punch that can fracture
aquarium walls but, more importantly, it has the ability to see a
vast range of colours. The ears of the great grey owl have such
unparalleled range and sensitivity that they can hear twenty
decibels lower than the human ear. The star-nosed mole barely fills
a human hand, seldom ventures above ground and poses little threat
unless you are an earthworm, but its miraculous nose allows it to
catch those worms at astonishing speed - as little as one hundred
and twenty milliseconds. Here, too, we meet the four-eyed spookfish
and its dark vision; the vampire bat and its remarkable powers of
touch; the bloodhound and its hundreds of millions of scent
receptors, as well as the bar-tailed godwit, the common octopus,
giant peacocks, cheetahs and golden orb-weaving spiders. Each of
these extraordinary creatures illustrates the sensory powers that
lie dormant within us. In this captivating book, Jackie Higgins
explores this evolutionary heritage and, in doing so, enables us to
subconsciously engage with the world in ways we never knew
possible.
This volume reviews our current understanding for how sex
determination is initiated and how it results in sexual dimorphic
development. Chapters discussing work on different model systems
provide a basis for understanding similarities that exist between
different species. Coverage includes discussion of sexual
development of the soma in C. elegans; sexual development of the
germline in C. elegans; sexual development of the soma in
Drosophila; sexual development of the germline in Drosophila;
sexual development of the soma in the mouse; sexual development of
the germline in the mouse; control of sex-specific behavior in
Drosophila; and control of sex-specific behavior in vertebrates.
* Uncovers the latest research findings on sexual determination and
sexual development* Detailed model systems illustrate species
differences and similarities* Thoroughly explains sexual
development across various germlines including Drosophila* Outlines
the origins and control of sex-specific behavior
Elwyn Simons has held professional appointments at Yale University
(1960-1977), Duke University (1977-present), and was the Director
of the Duke Primate Center (1977-1991) and Scientific Director
(1991-2001). He has authored nearly 300 scientific publications and
is the holder of many high honors. He is a member of the United
States National Academy of Sciences, the American Philosophical
Society, as well as many other professional associations. He was
elected a Knight of the National Order by the government of
Madagascar and has been the recipient of many awards including the
prestigious Charles R. Darwin Award for Lifetime Achievement from
the American Association of Physical Anthropologists. For nearly a
half century, Dr. Simons has dominated the study of primate
evolution. The volume summarizes the current state of knowledge in
many aspects of primate and human evolution that have been studied
by Simons and his colleagues and place it in a broader
paleontological and historical perspective. Elwyn Simons: A Search
for Origins contains the results of new research and reviews of
many of the critical issues in primate and human evolution during
the last half of the twentieth century as well as aspects of
African paleontology and primate conservation in Madagascar. The
authors are an extremely distinguished group of international
authorities on all aspects of primate and human evolution and
primate behavior. Although linked primarily by their connection to
Simons? own career, the chapters include a wide range of important
new works that are valuable contributions to the field of physical
anthropology and paleontology and are certain to be widely cited
and used in teaching.Several of the papers (Simons et al., Wing et
al., Seiffert et al., Gingerich, O?Conner) are broad reviews of the
history of research and discoveries in the fossil deposits of the
Fayum, Egypt that have formed the background of our understanding
of anthropoid evolution for over a century and will be important
researchers for students and researchers in primate evolution and
African paleontology. Similarly, broad reviews of the history of
primate paleontology and human evolution (Rasmussen, Pilbeam, Wood;
Sussman and Hart) will be essential reading in courses in primate
and human evolution as well as the history of physical
anthropology. Other authors describe new research results on early
anthropoid fossils from Egypt (Kay and Simons) Tanzania (Stevens)
and Myanmar (Gunnell and Ciochon). The chapter by John Oakley,
Professor of Law at the University of California addresses the
challenges to the teaching of evolution in schools- both public and
universities world wide. Another major focus of several chapters
are the primates of Madagascar. Two chapters are reviews of the
extraordinary radiation of fossil lemurs (Godfrey et al, Jungers et
al.). Two review the behavior and conservation of living lemurs
(Taylor and Wright) and the chapter by Tattersall bridges the two
major sections of the book by discussing about the biogeographic
history of Malagasy mammals.
The successful previous volume on this topic provided a detailed
benchwork manual for the most commonly used animal models of acute
neurological injuries including cerebral ischemia, hemorrhage,
vasospasm, and traumatic brain and spinal cord injuries. Animal
Models of Acute Neurological Injuries II: Injury and Mechanistic
Assessments aims to collect chapters on assessing these disorders
from cells and molecules to behavior and imaging. These
comprehensive assessments are the key for understanding disease
mechanisms as well as developing novel therapeutic strategies to
ameliorate or even prevent damages to the nervous system. Volume 1
examines general assessments in morphology, physiology,
biochemistry and molecular biology, neurobehavior, and
neuroimaging, as well as extensive sections on subarachnoid
hemorrhage, cerebral vasospasm, and intracerebral hemorrhage.
Designed to provide both expert guidance and step-by-step
procedures, chapters serve to increase understanding in what, why,
when, where, and how a particular assessment is used. Accessible
and essential, Animal Models of Acute Neurological Injuries II:
Injury and Mechanistic Assessments will be useful for trainees or
beginners in their assessments of acute neurological injuries, for
experienced scientists from other research fields who are
interested in either switching fields or exploring new
opportunities, and for established scientists within the field who
wish to employ new assessments.
